Hah! I love the first docking attempt of yours.
Definitely a bug. Next time try to swap open to solo or vice versa for reseting the instance.
Once a similar stuff happend to me. The biggest difference was however that I got stuck into the landing pad. When I was able to take off my vert speed was at max and almost knocked the opposite side of the station. That was epic.
Hope FD fix it soon, until then, just swap between game modes.
